Hashed out the approach between the President and Treasury on how to ban 64 byte transactions. It's a three stage process:
1. Executive Order to explain to the public how these things are only used by bad hombres
2. OFAC will add them to their list. Clearly anyonecanspend is Communist property - but Supreme Court might bikeshed the SegWit issue
3. A soft fork, but we can't wait for Bitcoin Core, they're too fucking slow

Thankfully since Brexit the UK can have its own Bitcoin friendly policy!

In any case, this comes from the #FATF and they're pushing that stuff globally. The EU does it slightly different from the UK, but most of the variation is in how companies enforce it. It sounds like Revolut picked the most shitty way.

It often boils down to cost: if forcing users to send coins back is cheaper than filling out some compliance paperwork, then that's what some companies will do. Especially the kind that doesn't give a fuck about its customers. Just keep in mind that isn't "just the law".

Sad bitcoin in Europe reality check - it’s getting baaaad..

I sent my friend his first bitcoin to Revolut ($30)

He had to verify the wallet it came from. Including my name, wallet etc. since I used a wallet which isn’t kyced (lol) they refused the Bitcoin - he was forced to send it back. Read that again. SEND IT BACK TO THE WALLET.

He couldn’t do anything with it. Fucked up.

But now he’s holding his own keys - he immediately understood why we bitcoin 😂 Barbara Streisand effect.

Watched the MIT Bitcoin Expo discussion about the Samourai Wallet and Tornado Cash prosecutions, and there seem to have been some misconceptions.

First, it is not "clear" that North Korea used Tornado Cash, as there appears to be ambiguity on how these funds are attributed. The reliability of said attributions has previously been a topic of debate in the criminal prosecution of Roman Storm.

We cover this here: https://www.therage.co/tornado-cash-trial-blockchain-surveillance-reliability/

Second, of course sanctions enforcement plays a role in the crackdown on privacy services, as a fully private financial system would make sanctions unenforceable, relieving the US of its most powerful economic warfare tool – some scholars may even go as far as arguing that sanctions enforcement is the main reason for AML frameworks to exist.

The idea that large transactions, such as for oil trade, would remain identifiable on chain despite mixer

Replying to @Pedro 🧨

Testing zaps for this note… we made six attempts to⚡zap this note, at pedromvpg@btcpay989117.lndyn.com, over a period of 19 minutes. In each case, we found that your lightning address server did not respond correctly. (The failure point was when we did a GET request to your specified callback URL: https://btcpay989117.lndyn.com/BTC/UILNURL/pay/lnaddress/pedromvpg.) Your server did not produce an invoice, thus the zap failed. We recommend that you use a cloud-based Lightning node which is optimized for Nostr zaps, to get your zaps working.

Unfortunately nostr doesn't fix this. And that "please list your social media accounts" question on ESTA applications isn't that innocent anymore either.

Assuming the First Amendment doesn't make a comeback, we'll probably see more encrypted group chats (e.g. MLS based).

Unfortunately those are not immune from rats, which governments could offer bribes for. So really we'll just go back to good old Soviet kitchen conversations with trusted friends, after everyone leaves their phone at the door.

And then Glory to Trump in public.

Looks like they’re running some AI agent to try and match foreign students to social media accounts. If the US State department doesn’t like the politics of the posts the visa is being revoked. The thing is everyone in the US is protected by the constitution, not just citizens. So this is overturning fundamental rights to free speech and due process.

There is no way for these students to contest this. Many people don’t put their full name on social media, often people have the same name. So not only will this violate students first and fifth amendment protections, it will likely be applied to students who simply share the same name or are confused with other students who expressed a political view the government doesn’t like.

If this program continues it means that no foreign student in the US is safe from arbitrary deportation. All

Cruise ship that plans to sail around the world every 3.5 years, carrying a combination of buyers and renters. According to this newspaper article some folks seem pretty happy, others are not.

At $100-320K plus monthly expenses of $3K - $7K it's a bit too expensive for my taste and I get sea sick. You can travel the world and live in very nice hotels and apartments on that budget. That said, it's not crazy unreasonable either and apparently many Americans spend more than that in dreadful land based homes.

What I find encouraging is that isn't a libertarian sea steading project. At least that wasn't the perspective of the people they interviewed. And the marketing doesn't emphasize that either. This is just a mainstream option now.

I'm seeing this new meme bubble up that Bitcoin, not even "crypto", is responsible for the demise of US democracy. This is nonsense.

First of all, everything that's happening in the last two months is a continuation of multi decade trends. It was obvious long before the whitepaper was published. Particularly an out of control growth of, and complete lack of checks on, executive branch power. Trump isn't even using a fraction of it. I find Dan Carlin's take on this stuff in his Common Sense podcast useful.

But that aside, crypto just isn't that important (yet). It's nice (or bad, depending on your views) that some people in power have at least heard of it, and own some, but that doesn't make it a crypto coup.

The highest estimate of crypto industry donations to this campaign I've seen is $400 million. That's a

Starbucks in most of the EU already serves your drink in glass or porcelain (but not for takeaway - imagine sitting down for ten minutes!).

For LED hypochondria there's probably easier technological fixes than going back to incandescent (though I have nothing against those if you don't mind the extra power bill and having to replace them all the time).

You can already cook steak yourself, no need to wait for McDonalds.

I don't understand what the wait for 2035 adds. Lower coinbase subsidy, that's for sure.

So the first half of Nexus is a great read. But it immediately falls of a cliff in Part II. That's where Yuval the historian is replaced by Yuval the trendwatcher.

In Part I he clearly illustrates how the witch hunt insanity was made possible by the printing press, without any algorithm involved. Then in Part II he considers the role of Facebook algorithms in the Myanmar genocide. He uses this to illustrate how AI changed the game, because for the time a non-human intelligence decided to promote one thing and not another thing. But how is that different from the non-human intelligence of market forces in the Middle Ages that spread the Hammer of Witches?

But it gets worse a few pages later, though maybe I'm just being my usual hardcore AI boomer... He cites a safety study where ChatGBT tricked a human worker on

Looks like three changes:
1) Legal reforms will make acceptance of Bitcoin by the private sector voluntary.
2) Taxes will only be paid in U.S. dollars and
3) the government’s participation in the crypto e-wallet (Chivo) will be gradually unwound.
4) For the public sector, engagement in Bitcoin-related economic activities and transactions in and purchases of Bitcoin will be confined

(1) and (3) seem fine, you could see them as bootstrapping measures. Now let's see if companies keep accepting it.

(2) is dubious, the treasury could just exchange BTC to USD to manage the volatility. But is this really about US dollar hegemony feeling threatened, or something more "mundane" such as:
a) the IMF doesn't trust the El Salvador government to handle this competently; or
b) a desire to keep surveilling money flows by forcing them through the fiat banking

More generally, I agree with James' observation that Bitcoin Core devs are paying much less attention to soft forks than they used to.

I can only speak for myself here. Part of the problem is that the current proposals don't excite me, yet. That's even after spending time at the op_next conference.

SegWit (which happened before I was involved) brought the promise of Lightning. Taproot lets you build cold storage with hidden fallback options.

I'm still waiting for MuSig2 to finally have broad adoption, something that's higher on my review list than new soft forks, and I barely get to it.

In that light, talk of a vault soft fork seems premature. The tool development is too far behind even for forks that already activated.

Similarly congestion control doesn't excite me. I'm general I'm skeptical of claims that the masses

NostRSS: does it exist yet?

I'd like to follow long form notes in my RSS reader, but I won't get to it during regular catchup of my feed.

The basic workflow would be to go to a website (self hosted or otherwise), paste in an npub and then get a RSS/Atom feed URL back.

The feed should only contain long form content (though the RSS feel URL could have params in it to select the kinds of events you want it to give you).

The urn:uuid of the feed should be deterministically derived from the npub, and the urn:uuid for each entry from the nevent id, so that I can switch over to another RSS feed provider without losing my (un)read marks.

Replying to @DanConwayDev

I was thinking that exposing files at exact commits would be simpler, but then I realized that to get the exact commit you would need an API that returns all references and HEAD (separate from the repository state event) and then I realized that to build a GitHub-like way to browse files on gitworkshop you'll also need all these things, plus a history of commits, metadata about all commits and so on, right?

Which brings me back to: why not do a full repository clone on the browser and get all that data at once? Is it just the big size of things?
